To alt whom it may concern:

Be it known that I, ISAAC L. MITCHELL, a citizen of the United States,and a resident of Cedar Rapids, in the county of Linn and State of Iowa,have invented an Improved Combined Stump-Puller .and Stump-Filer,

of which the following. is a specification.

Stump-pullers of a certain type are provided with a rotary drum on whichis wound a chain or rope that in Spractice is extended and attached tostumps which it is desired to extract or remove. I have made certainimprovements in such stump-pullers and I have combined therewith ahattachment adapted for swinging the extracted stumps laterally out oftheway and collecting or piling them in heaps.

The details of construction, arrangement, and operation of parts are ashereinafter set forth, and illustrated in the accompanying drawings, inwhich- Figure 1 is inpart a side elevation and in part a verticalsection of the combined machine. Fig. 2 is a vertical section of thepiler attachment. Fig. 3 is a plan view of the boom socket of the piler,together with the flanged rim of the winding drum forming part of thepiler attachment 4 is a cross section on line 4 4 of Fig. 2;

The piler attachment is mounted on the vertical driving shaft 1 of thestump-puller proper and the winding drum 2 of the piler is mounted looseon such shaft-but is adapted to be locked therewith by means which willbe presently described. Rotation is imparted to the driving shaft 1 froma motor or by hand power through the medium of a belt 3 running on alarge pulley 4 that is keyed on a horizontal worm shaft 5, the sameengaging a worm=wheel 6 which is keyed on the driving shaft 1. Thelatter operates with puller and piler. The details of construction,arrangement, and operation of the piler attachment will now. be de-.

scribed.

A wooden beam, termed a boom, 8'1s. se-

cured in a metal socket 9, and, in practice,

extends from the machine a considerable number of feet and is providedat its outer end with chains and grapples adapted for attachment to astump. The boom 8 being arranged at a slightupward inclination from theinner to the outer end, it is evident that the latter will be asufflcent distance above the ground to enable the. largest stump to beswung free.

In operation, the tackle having been connected with a stump, the boom isswung laterally and thus the stump is carried around tothe right or leftof the machine,

and is then released. Thus, extracted stumps are. successively collectedor piled in heaps right or left from the stump-puller, thereby leavingthe latter free to be advanced in a certain path or direction.

The socket 9 of .the boom 8 is provided with a horizontal base flange 10which is provided with a central opening and cast in one piece with thesocket 9 and with side ribs 9 that extend down from the socket and jointhe side portions of the annular flange, as shown best in Fig. 6. The.flange l0 rests on the top flange 2 of the drum 2 and is detachablysecured thereto by means of an annular collar or rim 11 and screw bolts12, as will be readily understoodfrom the drawings;

The several parts '11, 10, and 2 are provided with vertical holes 13 toreceive a pin 14: which serves to lock. the boom socket 910 with thedrum 2 when it is desired to operate the piler, or, in other words, toswing the boomlaterally. In other words, the pin serves as a means forlocking the boom and drum together, and it is obvious that in such case,the worm gear being set in operation,

the drum will be wound whenever it isproperly locked with the shaft 7.The means for effecting this areas follows: The shaft 1 is" providedwith a feather 15 and to this portion of the shaft is applied avertically adjustablesleeve 16 "which has 2. correspond ing longitudinalgroove for reception of the feather. The lower end of the sleeve isconstructed as a clutch adapted to engage a corresponding clutchformedon the drum 2.

Inother words, the sleeve and drum are provided with half clutches whichare adaptw ed'to engage when the sleeve is adjusted downward, so thatits lower end 17 enters asocket 18 formed in the upper head of the drum.The parts are shown thus engaged in Fig. 2, and consequently the drumwill be rotated with theshaft as may be required to wind on the rope orchain as, for pulling and extracting a stump. It will be under:

stood that during such operation, the pin employed to lock the piler'attachment to the drum will ordinarily be removed, so that the pilerwill be left neutral or at rest, although it is practicable to operateboth the piler'a'ndstump-puller simultaneously.

The means for adjusting the clutch sleeve up and downon the featheredshaft and thus, engaging or disengaging the drum 2, are constructed asfollows: The. upper end of the shaft 1 is constructed asa reducedscrew-threaded tenon to which a flanged nut 19 is applied, the samehaving a hand rimor wheel 19 for convenience in rotating it. The baseflange of such nut rests on a shoulder 16 formed in the enlarged socketed head of the sleeve, and the nut is confined or secured detachably insuch socket by means of a divided annular collar 20. Such collar issecured detachably to the head of the sleeve by means of lag screws 21.Thus, the collar 20 maybe easily applied to or detached from the nut 19,and the latter may be in turn removed, together with its handwheelattachment, from the sleeve 16..

The rope or chain a2 of the stun'ip-piler passes over a pulley 8 whichis journaled in a fol-k8 having a circular head 8 that is rotatablyconnected with the boom 8 whose rotative attachment accommodates itselfto the different angles at which the rope or chain to may extend whilebeing attached to or dragging a stump.

In brief, it will be seen that the several. parts of the piler may beall readily assembled and as easily detached from each other for thepurpose of convenience of storage or transportation.

The piler forms a comparatively inexpensiv'e attachment of thestump-puller and may be easily and quickly geared or connected theru'ithfor operation, and, as before intimated, may be operatedseparately from,or simultaneously with, the stumppuller, as conditions may require.

22 indicates the winding drum of the stump-puller proper on which achain or rope as is wound, the same extending n practice far enough toadapt it for attachment in the proper manner to a stump that is to beextracted. Said drum 22 is keyed on a vertical shaft 23 having itsbearings in the portable frame on which all the other parts of theapparatus including the motor are mounted. A large gear wheel is keyedon the lower end of the shaft and a pin ion 25 is mounted on the drivingshaft 1 and has a feather or spline connection with the same, but isadapted to be raised and lowered as indicated by dotted lines in Fig. 1.

When the pinion 25 is in the lower position indicated by full lines, itengages the gear 24: and consequently when the shaft 1.

semen is driven, the drum 22 of the stump-puller willbe rotated. On theother hand, when the pinion 25 is raised, as indicated by dotted linesin Fig. 1, .out of engagement with the gear 2d-which may be effected bymeans of a pivoted hand lever 26 or other device it is apparent that thestump puller is thrown out of action; or, in otherwords, the windingdrum is left at rest.

It will thus be seen that both the stump puller and the piler attachmentmay be rigidly connected with the driving shaft 1, so that both may beoperated simultaneously, or that either may be so connected with theshaft 1 that it may be driven or left at rest.

It will be seen that through the medium of the worm gear, the drivingshaft 1 may be held locked when the motor is disconnected, and thusWhatever tension has been applied to the ropes or chains of thestumppuller and stump-piler, may be retained. I thus dispense with thenecessity of employ ing a pawl or other special locking device foreither the stump-puller or piler.

What I claim is l. The improved machine comprising a vertical drivingshaft and means for rotating it, a rope-' winding drum constituting partof a stump-piler, a device for detachably engaging said drum with theshaft, and .a boom extending laterally from the shaft and adapted forsuspending the rope of the piler drum, and. means for locking the boomdetachably\Vilth the drum, whereby the. latter may be rotated to wind onthe rope and then the boom locked with it for swinging or lifting astump, substantially as described.

2. The improved machine comprising a vertical shaft and means fordriving it, a stump-pilot attachment consisting of a ropewinding drummounted loose on the shaft, a device for locking it detachably with saidshaft, a laterally extended boom, means for supporting the boom, thesame formed of a socket having a circular base flange, and an annularinturned flange on the drum which receives the flange of said socket,and a device for locking the two flanges together as described, so thatthe drum may be rotated independently of, or together with, the boom, asthe piling operation requires, as described.
